Replaced sentinel value with empty table
Made api objects stringify nicely
Generalized paths ready for API loading
Implement API autodownloading

Continuation of damien/cc-scripts#10
Renamed `loadAPI` to `api.load` for consistency with other functions
Removed installer api - part of damien/cc-scripts#12

The cc_scripts module now handles downloading files (to make bootstrapping easier)
Fixed minor error introduced in startup
Made the bootstrap more bootstrapped

Now downloads /api/cc_script/, and delegates installation to that.
Restart no longer required.
